Stars govern the universe; they generate violently, and decay enormous explosions, and fills the universe with dust stellar, and those are the building blocks of life; each atom within the human body produced within the sub fiery a star, fate is too linked to the fate of stars; therefore, life begins from here !.
There is in the universe more than a hundred billion stars, and contains more than a hundred billion galaxies; The number of stars outnumber the grains of sand on the ground, and each star great capabilities; where creates the basic materials for everything in the universe, including living organisms, but most of the stars are very far away do not know about them only a little, but there is a star close to us, we have learned from a neighbor that everything we know about the stars.
The sun shows us the most powerful body in the universe landmarks, it is a ball of superheated gases light up our solar system since 4.6 billion years old, and controlled life on Earth, and away from us the sun 62 million miles, and this means that the huge size to allow for a capacity of one million planet the size of Earth, where diameter exceeding one million kilometers.
Horsehead Nebula
But the staggering size of our sun is in fact a small matter compared to the big stars in the universe, there is a star called Rigel, which is larger than our Sun five million times .. What a horror!
There is a star called Betelgeuse, Rigel, the largest of the incredible 300 any time .. if he occupied the place of our sun reached Jupiter .. oh nice !.
This giant then appears, and call it VY Canis Majoris, a star of the largest discovered so far; it grows up a billion times our sun .. no comment !.
We find that some stars left alone, others take a partner to orbit one around the other, then combine to form large galaxies containing billions of stars, and all the unique star, but it generates the same way in the form of clouds of dust and gas called the "Nebula" .. wander in space for a distance of billions of miles, and take amazing forms such as "flame Nebula," and "Horsehead Nebula" and "Orion Nebula".
Flame Nebula
We see the early stages of form star, as all it takes to form a star is hydrogen and gravity and time, where the pull of gravity dust and gas into a giant whirlpool, pool gravity things together, and when gravity material collected and Tdguetha in small areas, they Stschen Inevitably, this simple law in Chemistry, as the compression generates a rise in temperature over the hundreds of thousands of years, becoming more and more cloud density, and form a giant revolving disk larger than our solar system as a whole, and in the midst of pushing gravity gas to form a super density and temperature football, and rising pressure to emerge jets gaseous huge center , and this is what shows the amount of violence in the process of forming the star, and that these jets stretching along light years, Vthafez gravity on pressure, where it is absorbed gases, dust and particles that collide with each other to breed, and thus more heat created over half a million years.
Here is getting smaller size of the star young and getting brighter and hotter, which will exceed the temperature in the core eight million degrees, and at that high temperatures can atoms of gas to begin to join forces to release huge amounts of energy, why not a birth One to Watch for millions or billions of years or perhaps thousands of billions of years, where the stars produce large amounts of heat and light over billions of years, but that requires huge amounts of fuel.
In the early twentieth century, we did not know what the fuel, then the biggest problem faced by the physics at the end of the last century, which sets out the stars energy source, so what we have to do is to look at the sky; to realize the extent of the shortfall in our knowledge, we have we need to discover the secret of the stars, as we need to know the tremendous source of energy, to pay the star for billions of years.
It was discovered that one of the men genius Albert Einstein, who proved his theories that stars derive their energy from within atoms, the secret of the stars is the equation of "relative" to Einstein; energy is equal to multiplied bloc in speed optical box, in the sense that the basic material that make up the human body is a concentrated energy intensified in the atoms, which make this universe, where science is now trying to simulate the energy source in the star; to control the power integration mechanism that drives the star by gravity, and this is the big size reason, massive stars are, and need to be so much gravity to press the star, and produces the amount of enormous heat enough to ignite nuclear fusion.
This is the secret of the stars, but this shining stars; Vanshar in the soles of the star generates explosive power equivalent to a nuclear bomb billion every second .. If Valndjem is a huge hydrogen bomb, why not fizzle if? This is because gravity pushing the outer layers of the star, Valjazbah fusion locked in a great battle, there is a constant tension between gravity, which wants to crush the star, and the energy released by the fusion process, and you want to destroy the star, and this tension, any balance process, generate a superstar continues in this conflict Throughout the life of the star power.
And those battles inside the star generate light, but most of the stars so far away, so that up to us its light after hundreds or thousands or millions or billions of years, so when the Hubble Space Telescope looks to the parties to distant universe, will see the light that moves billions of years ago, and this light that we see Today the star Rigel, that left the star when planting our ancestors ground before eight thousand years, and the light from Betelgeuse passed since Columbus America was discovered 500 years ago, and even the light from our sun takes his arrival to us eight minutes, so I would like to quote any of the Holy Quran:) I swear by the stars locations. It is a great oath, if you know ((accident: 75.76).
When extinguish the star in the final moments destroy everything that surrounds him from the moment of birth, every star Smothers will implement its fuel, and then win gravity battle with fusion, and launches a series of events that will destroy the star .. Vhmsna is no exception; every second burn 544 million tons of fuel hydrogen in the core, and this rate will be implemented hydrogen after seven billion years ago, while the exhaust hydrogen, Vtbti fusion process in the soles of the star, and this gives gravity preference to pay fusion less towards the outside of the crush of gravity star, but gravity is contained Vtschen the outer layers of the star .. and Khna when we Venture heats the gas, and so on, the sun will spread to the top rather than a million miles in diameter as is the case now .. Stantfaj even with a diameter of almost one hundred million miles, our sun to become a red giant.
Imagine sunrise after seven billion calendar year, not just a small yellow tablet rises beautifully, but you will see a red disc huge and swollen slowly rising above the horizon, and when the sun shines fully in the sky will send the heat on the ground where will be thousands of degrees .. The ocean Stgla, and the mountains will melt , and we will eliminate another beautiful day on the ground, then the star Siegmr swollen earth, but the huge red star destroys itself, and becomes inwardly unstable serious degree.
Since there is no hydrogen remaining to refueled, it begins with the star burning helium and his brother-carbon, Widmer himself the star from the inside out, is called violent waves of energy from the subsoil to the surface, unleash the power of these outer layers of the star waves, crashing slowly, and quench star nor left but thick soles and extremely hot, red Valamlaq become a white dwarf, and when the star white dwarf stage be fusion process has stalled, the engine finally stopped and will end our sun of her life Kgazzm white smaller than the Earth, but the densest of them a million times, White Vaelkezm something spectacular, it is very thick .
If you have received a piece of white dwarf the size of sugar cube and Odatamoha on the surface of the earth, it will be dense to the point of impenetrable surface, in the heart of the white dwarf Astronomers believe there is a huge crystal of pure carbon, it is an urgent universal diameter thousands of kilometers .. think the idea of becoming a sun dark and cold block of ash material, somewhat sad, but it will be an urgent caliber trillion carats, think about it .. urgent in the sky!
Lived massive stars fast life, and its light shining, strongly subsided, but life emerge from destruction; Fajmod big stars lay the foundation stone of the universe from the seeds of life itself, for less than 600 light years from Earth distance, which is about the huge star Betelgeuse on subsiding scale space on at least, as it is the latest of our sun; it is due to the millions not billions of years, but the fusion inwardly much stronger, Valndjem Betelgeuse is totally different from the sun, as it is a giant red color; and because of that this star is greater than much sun size, means that what being in the core is quite different from what is happening in the soles of the sun; where the big stars generate pressure and temperature is greater than anywhere else in the universe.
Valjazbah in the star strong Betelgeuse is so that they can integrate atoms more and more of the soles of the star, and similar to the factory make heavier elements Vothagl, and this also leads to the destruction of the star, what to make iron even eliminates the star; Iron is is the most dangerous elements in the universe; it It absorbs energy from the moment the big star arises, and when he makes the star iron, remains for him a few seconds to live, and trying the star shed energy in those iron ball and trying melted down, but he fails to it, and thus deprive those ball star of energy.
Once the start that the iron is formed in the subconscious even be the star has been sentenced himself to death; where the battle between gravity, which is trying to crush the star, fusion which is trying to blow it up, a battle that ended, with the iron of fusion deadlocked; Valjazbah always win while the iron soles collapses , the external layers of the star hit him Vidoje a massive explosion, and is considered the most violent event in the universe; During the few seconds generate Star Supernova energy larger than our sun after a few seconds from the start in the iron-making, and this image shows "the Crab Nebula," coupled with the explosion of Supernova.
Orion Nebula
The all Nebula custody of the Stars; bred millions of new stars, but the birth is not visible parts, and the most exciting in the mist they are not glowing and beautiful gas, but the dark parts, and we find in the dark parts of regions of gas and thick dust, and this place which is witnessing a real active with respect to the formation of Stars cloudy dust is very dense, so that ordinary telescopes are unable to penetrate all, there is nothing more important than the stars for us, but the way its formation remained mysterious for a long time, we were unable to watching it, and we could not see the first moments of the birth of a star until 2004.
When the "NASA" launched telescope Spitzer space to search for the unknown secrets in the evolution of the universe process, as the Spitzer telescope for imaging infrared, does not see only the heat, Vijtrq thick dust of the nebula, is available for "Spitzer" see new stars when she was born at home, and this amazing show's first moments in the life of the star.
Where exploding star to become a Supernova, Article from deep inside the star sends shock wave in the space of the amount of heat and disorder explosion, Vti_kl heavier elements, including gold, silver, platinum, and since that time is short to form the elements, they are the rarest and most valuable in the universe; in gold, silver and everything another is formed by the explosion of the star and the enormous energy bar, and come to us that way, but even after the most violent explosions in the universe, it leaves something behind him.
But as long as the scientists think that after the Supernova explosion explode the star to small parts will not be leaving him something, but we believe this is wrong, since there is a product of the Supernova explosion of some of the strangest substances known to science, which is called the star neutron .. It nuclear material solid It is the coolest cases of material in the universe, we have sub-dense become a star neutron, with a diameter of about 30 kilometers, which is very heavy because it is very thick, mere centimeter cube the size of sugar cube of material neutron star, equal to the weight of all the cars in the United States of America; Valndjem dormant does not leave only the body of the neutron star, but called the new elements away in space.
These clouds contain the foundation stone of the universe, and everything we know and love Him built of this interstellar dust alone Supernova, which have enough energy to melt these basic life elements, there is no life without Supernova and there is no you and me; When subsided stars and left behind a dust launched Star Supernova in space, This universe has turned to dust stellar full of elements such as hydrogen, carbon, oxygen, silicon, iron, a raw material for building new stars and solar systems, and Guillaume, of course, what we see all around us exploded in the past from the soles of the star.
You might wonder about the nature of interstellar dust? You stellar dust; because every atom in your body is produced inside the sub fiery star .. what atoms in your right hand may come from different star of the atoms in your left hand, but you Walid star in every sense of the word.
Stars extinct a long time ago secured the interstellar dust of the origins of our solar system, planets, and everything on them, then you are made of carbon and oxygen if, and apply the iron in your blood, and generated all those things inside the soles of the star, not the other way to get them.
When you think of material stars, Look around you, all you have done it and making it the world, the source of the soles of the star exploded a long time ago, even the atoms in our sun have been recycled into blocks bounced in space Stars dormant for a long time.
Our sun is Araptna; real Voldtna died in Supernova explosion to give birth to the elements that formed our body to live in the age of the stars, but it will reach its end; a few Hydrogen in the universe and will exhaust after trillions of years, and when it is left hydrogen will not be formed new stars; we live in a very short period of time in history universe, but our stars still illuminate the sky .. Nujoma create life as we know it, but it will not last forever, Sintefi twinkle star sooner or later, First Stntefi big stars, then medium-sized Khmsna stars, and the successor smaller, and after trillions of years Stkhvt in turn, and will become the universe slowly without mercy, and cooler and more darkness, turns off the last star, becomes the universe dark, and ends so the stars age; to live in the life of the season in the universe, so to speak last few billion years, and that makes me at least appreciate the nature of the case now; because they were not and will not So always be stars .. will continue to form our universe for the time being, and laid the foundation stone for new worlds, creating a new star and fill the darkness with light.
